Here’s a direct link to NASA’s data set. April 2015’s global mean surface temperature was 0.75°C higher than the long-term average. Only April 2010 was warmer.
The data also shows that the four-month period to start this year (January through April) was the hottest four-month beginning of any year on record.
The past 12 months are the warmest 12 consecutive months on record, breaking the record set the previous month.
If you can think of any excuse to deny anthropogenic global warming, let me know. It’s probably already debunked on my 14 Poor Excuses page.
